“…However, the sediment is finer and consequently more transportable when distilled water is applied. These results are in agreement with results on susceptibility of silt loam soils to physical degradation under rainfall simulations using tap and distilled water (Borselli et al, 2001). Basically these authors state that the water quality used in laboratory simulations needs to match that of rainfall because the use of distilled water in the laboratory brings the soils' behavior above a degradation threshold, and they conclude that good quality water should always be used for every type of soil.…”

“…In order to monitor rainwater quality, water samples were taken every time the water tank was re-filled. The rainwater used in the experiments had an average electrical conductivity of 0.36 dS m −1 , which met the electrical conductivity standard (less than 0.3-0.5 dS m −1 ) suggested by Borselli et al (2001). Total suspended sediment (g L −1 ) in the rainwater was 1.1 orders of magnitude on average less than the sediment collected in runoff.…”

“…With an average falling height of 1.8 m, the kinetic energy applied on the soil surface was 12.5 J m −2 mm −1 . Demineralized water was used instead of tap water to prevent flocculation problems with dispersible soil material [30], [31]. As the total load of ions in rainwater is very low (the annual average electrical conductivity EC 25 was below 20 µS cm −1 at the official Dutch sampling site Beek [32], about 10 km from the soil sampling site) the physico-chemical impact of demineralized water on soil particles is considered to be the same as for rain water.…”

Soil Organic Carbon Redistribution by Water Erosion – The Role of CO2 Emissions for the Carbon Budget

A better process understanding of how water erosion influences the redistribution of soil organic carbon (SOC) is sorely needed to unravel the role of soil erosion for the carbon (C) budget from local to global scales. The main objective of this study was to determine SOC redistribution and the complete C budget of a loess soil affected by water erosion. We measured fluxes of SOC, dissolved organic C (DOC) and CO2 in a pseudo-replicated rainfall-simulation experiment. We characterized different C fractions in soils and redistributed sediments using density fractionation and determined C enrichment ratios (CER) in the transported sediments. Erosion, transport and subsequent deposition resulted in significantly higher CER of the sediments exported ranging between 1.3 and 4.0. In the exported sediments, C contents (mg per g soil) of particulate organic C (POC, C not bound to soil minerals) and mineral-associated organic C (MOC) were both significantly higher than those of non-eroded soils indicating that water erosion resulted in losses of C-enriched material both in forms of POC and MOC. The averaged SOC fluxes as particles (4.7 g C m−2 yr−1) were 18 times larger than DOC fluxes. Cumulative emission of soil CO2 slightly decreased at the erosion zone while increased by 56% and 27% at the transport and depositional zone, respectively, in comparison to non-eroded soil. Overall, CO2 emission is the predominant form of C loss contributing to about 90.5% of total erosion-induced C losses in our 4-month experiment, which were equal to 18 g C m−2. Nevertheless, only 1.5% of the total redistributed C was mineralized to CO2 indicating a large stabilization after deposition. Our study also underlines the importance of C losses by particles and as DOC for understanding the effects of water erosion on the C balance at the interface of terrestrial and aquatic ecosystems.
